PORTLAND, Maine (NEWS CENTER) -- Downeaster trains 681, 683, 684 and 686 are cancelled for Monday, Tuesday and Wednesday of this week. There were cancellations last week as well, and Amtrak said it's because of track maintenance.

All other trains will operate on the normal schedule, but because of continuing track maintenance, most Downeaster trains will have a delay of about 10 to 35 minutes.
